citizen of the .United States, vresiding at Ch1 i cago,in the county of'Cook and State of Illinois, have inyentedcerta/in new andusefulImprovements in Adjustable ..Lamp- Holders,` of which the lfollowing isja. .de-

Pro- .jectedbetween the arms 12 and into the 'sleevel'is theforward end 14 'of ahandle l or, operating 'lever"1.5, which is pivota'lly be founddesirable:

7 l further object is to so constructy said device'that the variousmanipulations mayv be made by meansof-a single-"han'dle-or lever.

Moreover, it `is my, purpose to solutilize saidllamp as' .toproject'light therefrom to'- f ward the rear of a vehicle -for'signal orother purposes in addition vto that ,used inlv front ,-Qall, of which ishereinafter more', particularly described and deinitely pointed Jout inthe claims.

In the example illustrated,l the stationary part1 has a vertical borein the bottom thereof in which 'is journaledl atubular member v8, having4 a crank-arm 9-formed thereon for the purposeshereinafter set forth. .Said tubular member isiprojected below` thestation# ary casing-.and 'has rigidlyclamped thereto,

a' sleeve member 10 havinga vertical slot 11,

Extending laterally "frein the' casing- 1 s v a 'rocking member17journaled in such casing -upon a horizontal axis. The journaled.

portionv 18 has 'a crank` member 1 9 rigidly a bifurcated connecting.member 22 and, bolt orpin )23; 'Al- The rockingmember 17 has thereonanenlarged laterallyjextended cas'- ing 24, Figs.`-2, 4 and -5,ithe upperportion y of which his provided with a vertical bore in whichis-journaled a standard l25, which is .rigidly fOrmed'upon, or connectedwith., .a lampca'sing 26,' for which it forms a,piv'

otal support.A crank-arm27 is rigidlyattached to the pivotal portion orlower end 'of thestandard 26, which arm is connected by means of apitman 28', to. a wrist-pin 29 upon the crank arm4 A swivel. 28 is inf'lterposed in the pitman 28, to enable the part '24 to be oscillate'dwithout `:'mjuryto saidpitman.

The casing 26.- is intended 15o-contain ltwo electric lamps of any `wellknown construction, one of which, 30 indicatedv 1 n dotted lines in Fig.2, is intended to project light in front and'the other, 31, is' intendedt0 project light towardthe rear. lThe lamp 3l is separated from thelamp30 by means of a partition 32 in the casing. The lamp 30 isconnected by means of wires 33, 34 1ndicated in dotted lines in Fig.2and shown in full ylines in Fig. .3, with a source of electric energy35, while the la'mp 31 is connected therewith by means of wires 36 and37. All of 'said wires are led through the casings and tubesrespectively as indicated in ldotted lines in Fig. 2, to and throughconduits or passages in the handle lever where the wires 33 and 34 areconnected with the terminals of an electric switch 38 and the wires 36and 37 with those of a switch 39.l

In `order. that the handle lever may not .become accidentallymisplacedwhen not held by the user, I tighten the nut on the bolt 16, soas to cause a suiicient degreeof -friction upon the lever to hold itagainst abnormal displacement.

For a like reason, I interpose between the stationary part 1 and theupper end of the sleeve member'lO, a springwasher 10a.which should beunder sutlicient compression to frictionally resist the rotation of thesleeve and hold it against accidental movement.

In the example illustrated I have contemplated using both' lamps -forwhat are commonly known as spot-lights, or in other words, forsearch-lights or for signal purposes; in which cases both of theswitches indicated .would be normally open, but' it is obvious that-oneor both may be normally closed.

The operation of the apparatus is as follows: Thelamp casing maybetilted so as to throw .the lights up orvdwn by merely tilting thehandle-lever vertically upon the fulcrum pivot 16, when the pitman 21,acting upon 'the ,crank-arm 19, will cause the casing or rocking member,to be tilted upon a horizontal axls, thereby carrying with 1t thenormally vertical lamp support A25. .A

lateralA movement of the lever in turn serves 50 to actu-ate the',crank-arm 9 which, through the pitman 28 and crank-a'rm 27, results inlmoving the lamp upon said normally vertical axisto throw the light rayslaterally in either direction. varied indefinitely so asto impart asuinciently universal movement to the lamp to meet'all requirements ofthe user.

If used upon an automobile at night, the operator may so manipulate thelamp 30 as to light the road while turning curves, ascending ordescending hills, for reading signs, or for any similar purpose; while,by

closing the switch 39, the light 31 maybe directed toward the rear asa'warning or to enable the driver to see what is behind.
